WINDMILL.

To all whom it may concern:

Be it known that we, NICKOLAUS WAGNER and JAcoB VVAGNER, citizens of theUnited States, residing at Caldwell, in the county of Canyon and Stateof Idaho, have invented certain new and useful Improvements inlVindmills; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in windmills, and whileespecially designed for use in connection with irrigating arid fields,may be employed in many other rela:

tions where the generation of power is required.

One of the principal objects of the inven-' tion is to provide a machinethat is not only of a simple and durable structure automaticallyadjusting itself to the changes in the direction of the wind, but whichwill produce additional power.

Another feature ofthe invention is the employment of a pair of windwheels of different diameters mounted on the ends of a crank shaft whichextend for different lengths from the crank.

While the invention is not restricted to ,7

the exact details shown and described, still for the purpose ofdisclosure reference is had to the accompanying drawings illustrating apractical embodiment of the same, in which drawings like numeralsdesignate the same parts in the several views, and in which Figure 1 isa perspectiveview of a suitable support with the invention applied. Fig.2 is a plan view with the wind wheels omitted, and Fig. 3 is a verticalsection on the line 3-3 of Fig. 2.

1 designates a suitable structural support provided with the bed2centrally apertured, as at 3, and having mounted thereon a circularmetal track 4.

5 designates the bed plate which is of annular construction, and isprovided with annular grooves 6 forming a raceway for balls. The baseportion of the bed plate 5 is provided with a cylindrical extension?registering with the opening 3 in the bed.

S designates the annular base of a revoluble support, which is of thesame construction as the bed plate 5,.the annular base 8, however, beingslightly less in diameter, and the cylindrical extension 9 beingSpecification of Letters Patent.

slightly greater in diameter. The revoluble member is also provided withan annular groove 10 alining with the groove 6 and forming therewith araceway for the reception of the balls 11 to provide a ball bearingsupport between said revoluble member and said bed plate. A pluralityofguide members are arranged around the edge of said 'bedplate and consistof the base sections 12 and the offset projections 13 extending in theopposite direction to said base section over the edge of the annularbase 8 of the .revoluble support. The guide members and the bed plateare rigidly secured together and to the bed by means of bolts 14 passingtherethrough. On .the annular base 8 of the revoluble support aremounted the bearings 15 for the crank shaft, and these bearings may beprovided with the lubricating cups 16.

17 designates the pitman connected to a crank 18 forming a part of acrank shaft, one end of which extends a greater distance from said crankthan the other.

In the drawings the shorter end of the crank shaft isdesignated as at19, and the longer end as at 20, and the longer end is one-third longerthan the shorter end. One of these ends carries a supporting wheel 21,and the other may be provided with a carriage 22havin a pair of smallerwheels, said wheels being adapted to engage the circular track 4. Thecarriage 22 is so arranged that it may always engage the track, but thewheel 21 only comes into engagement therewith when it is necessary tosupport the weight of the shaft and prevent the same from bending orstraining in the case of heavy winds or other causes imparting unduestrain on the shaft.

23 represents one of the wind wheels mounted on the long end of theshaft 20, and is provided with any suitable form of vanes, the diameterof said wheel, however, being greater than the diameter of a smallerwheel 24 mounted on the short end of the shaft 19, in the drawings thedimension of the larger wheel 23 being one-third greater than that ofthe smaller wheel 24.

The objects of providing a shorter end for the crank shaft and ofplacing the smaller wheel 21 on the same are z-By mounting a wheel ofany size as close as possible to the bearings of the shaft, it Will begiven a firmer support in its bearings when operating in high winds; andby making this particular wheel smaller than the outer wheel 1t 1s lessliable to 1n ury 1n lngh winds and does not deliver so great an excessof power as would be the case were it made larger. Again, by placing thelarger wheel on the longer end of the axle, it has a greater leverage inadjusting itself to the wind and will therefore be more certain to moveinto its adjusted position in light winds, than would be the case if itwere placed on the short end of the axle.

Any suitable braking means may be provided, and in the drawings isrepresented at 25 as comprising a. spring band secured at one end to theextension 9 of the revolving member and at its other end passing over abraking or friction pulley carried by the shaft, the free, overhangingend of the spring band being connected to operating means not shownleading to the ground.

hat we claim is:

1. In a windmill, the combination of a support, a crank shaft journaledthereon, the said shaft from its crank being substantially one-thirdlonger on one side than on the other, a wind wheel carried by said shaftat each side of its crank, the wind wheel on the long end being of adiameter one-third greater than the wind wheel on the short end of saidshaft, a wheel 21 car ried by the short end of said shaft, and acircular track on which said wheel runs and adapted to support the same,substantially as described.

2. In a windmill, the combination of a stationary support; a revolublesupport thereon ball bearings between said supports a crank shaftjournaled on said revoluble support and extending unequal distances ateach end beyond the same; a wind wheel carried by each end of saidshaft, that on the shorter end being smaller than the wheel on thelonger end; a carriage carried by said longer end; a supporting wheelcarried by the shorter end of said shaft; and a circular track on whichsaid carriage and wheel travel, substantially as described.

3. In a windmill, the combination of a stationary support coi'nprisingan annular base and a cylindrical uprightextension, a revolnble supportcomprising an annular base of less diameter than the annular base ofsaid stationary support and provided with a cylindrical extension oflarger diameter than the cylindrical extension of said base support,said annular base portions being provided with annular grooves formingraceways, balls disposed in said raceways between said g'ooves, rigidguiding means having offsets projecting over the edge of the base ofsaid rcroluble support, a crank shaft mounted on said revoluble support,and a wind wheel carried. by said crank shaft, substantially asdescribed.

4-. The combination of a stationary support, a revoluble support mountedthereon, hearings on said revoluble support, a. crank shaft mounted insaid bearings, rotating members comprising a carriage and a. wheelcarried by said shaft and adapted to roll on said stationary support,substantially as described.

' In testimony whereof, we atlix our signatures, in presence of twowitnesses.
